How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-1800, inspect your project dependencies for Github.com/sjqzhang/go fastdfs:

inspect dependencies for github.com/sjqzhang/go-fastdfs

Analyze the terminal output to locate any version of Github.com/sjqzhang/go fastdfs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.5-0.20230408141131-61cbff5124c6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-24: Path Traversal: '../filedir', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "../" sequences that can resolve to a location that is outside of that directory. In Github.com/sjqzhang/go fastdfs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

sjqzhang go-fastdfs up to 1.4.3 is vulnerable to path traversal in the function upload of the file `/group1/upload` of the component `File Upload Handler`. The attack may be launched remotely and the exploit has been disclosed to the public and may be used.
